Better bats
To get a special bat (in any mode except tee-ball) you must get a double play. You can walk a man. When the other player comes up, he might hit a single. Note: Get a fast pitcher to run to first and tag the player out. Note: Sometimes you may strike out the person or not get him if you have two outs.
Better performance
Put Amir Khan and Achmed Khan on the same team and both of their skills will increase. The same happens when Ashley Webber and Sidney Webber are on the same team. Major league players will have increased skills when playing for their real life team. For example, Randy Johnson will perform better when playing as an Arizona Diamondback.
